Message

At Steak Guys Butcher, I analyzed sales, inventory, and customer data with SQL, Excel, Power BI, and Python, reducing weekly report preparation time by approximately 50%. I also developed dashboards for revenue, gross margin, and stock turnover, and used sales analysis and demand forecasting to contribute to a 60% reduction in stock spoilage.

At Francistown digital club, I developed web applications and management solutions for partner institutions, connecting SQL and MongoDB data layers to Power BI and Tableau reporting. My work has also included maintaining analytics data pipelines at Visible Inc and building a crop-yield prediction project using machine learning.
